Anuj gets pocket money from his father everyday. Out of the pocket money, he saves 2.75 on first day,

3 on second day, 3.25 on third day and so on.

To find:

total amount saved by Anuj in 8 days

Step-by-step explanation:

• The amount saved by Anuj forms an AP $2.75,3.3.25,,,$ and on eight day  amount saved by Anuj is $a_{8}=a+7d=2.75+7\times0.25=4.5$

• $S_{8} =8(a_{1} +a_{8} )/2=4\times(2.75+4.5)=7.25\times 4=29$

So the final answer is 29
